I got a Logitech Bluetooth Keyboard (K810), English keyboard layout, which I would like to use with my Android smartphone (LG G2). The pairing of the devices works fine, but I can't get it to display German language characters such as ö, ü, ä etc..

Those characters, however, work fine when I use the keyboard with a Windows-PC, after having changed the keyboard-language-settings in the OS.
Is there a way to do the same thing on Android?

In fact I would need to be able to toggle between the two languages (Eng & German), since I prefer to use the English-keyboard-layout when writing in English and the German one when writing in German. That's easy on Windows, just press the Windows-key together with Space, but how to do on Android?

Any idea how that could be accomplished? If toggle is not possible, then I would prefer to permanently change the keyboard input language on my LG G2 to German.
